Can AI-based automated wind turbine blade damage detection detect structural damage?

AI-based automated wind turbine blade damage detection has significant economic value. This article proposes a novel memory-aided denoising autoencoder for unsupervised blade damage detection, which detects structural damages with a denoising autoencoder and detects logical damages with a designed memory system.

Can Aquada-SEG be used to segment wind turbine images?

Blade segmentation is a fundamental task for blade damage inspection in the field without stopping wind turbines. This study proposes an AI-based method AQUADA-Seg to segment the images of blades from complex backgrounds by fusing optical and thermal videos taken from normal operating wind turbines.

What is the largest wind turbine blade dataset?

To the best of our knowledge, our dataset is the largest wind turbine blade dataset to date. All blade videos are taken with DJI Zenmuse H20T 2 or DJI Mavic 2 Enterprise Advanced 3 while wind turbines are in normal operation. We fixed the frame frequencies of the optical and thermal cameras to 30 FPS.

Can thermal modality detect surface damage in wind turbine blades?

Optical modality can be used to detect surface damage, but cannot be used to detect underneath damage, which is much more important than surface damage in wind turbine blades. Meanwhile, thermal modality can help to detect underneath damage.

How to improve wind turbine blade segmentation performance?

This verified that we can indeed improve the blade segmentation performance by utilizing temporal complementarity with a designed memory. In addition, since wind turbine blade videos are periodic, there is an upper bound to improve the segmentation performance by increasing the memory size.
